Atriogenic Flow Across a Restrictive Subaortic VSD: a Sign of Stiff Left ventricle

Mohammed Islam, Gabriel Fernandes, Wei Li, Michael Henein


Atriogenic Lt-Rt shunt across a ventricular septal defect is an uncommon finding, but reflects a stiff left ventricular cavity with raised end-diastolic pressure. These findings explain the left atrial enlargement and supraventricular arrhythmia. Thus, those shunts should be considered as safety valves to release the raised left sided pressure into the low pressure right ventricle.
